is there a good way to prevent the probe's from failing?
In my opinion, no not completely.
BUT obsessing over it won't help either.
Follow the rules:
RV tp only....and talk to the occupants about not using too much.
Put in a dose of digester/deodorizer
Don't dump too often; get at least half full and then drive a bit to aggitate.
Then don't let it get completely empty while not in use.
5 gal or so of plain water in there while driving down the road should splash around enough to give it a good rinse.
(edit) Forgot to say: When not in use, the water left in ALL of the tanks should be "super chlorinated" to prevent nasty stuff from GROWING in there.
Don't worry; be happy. :B
